I have used him twice. He has done a good job both times. The latest carb I got about 4 years ago...a 750 HP for my 331. I had it dyno'd along with air/fuel monitoring and the AF was almost right on. I could have left it alone, but I went ahead and up'd the jets by 1 on primary and secondary. I did have to change the PV from a 4.5 to a 7.5 to fix a off idle stumble. Otherwise good to go.

Yep sounds like the same rule's as every other track that run's the 2bbl's. Don't get me wrong, I'm not saying that I'm the best but I do know that my stuff make's real good power. And for somebody to say that they have a money back guarantee, If you have something else that run's better is pretty much saying that they are the best. And I'm sorry I didn't see Dave Braswell's or Mike Laws's name's anywhere.
